SEMICONDUCTOR DEVICE HAVING FUSE CIRCUITRY ON CELL AREA AND FABRICATING METHOD THEREOF

摘要

PURPOSE: A semiconductor device having fuse circuitry on a cell area is provided to increase integration of a semiconductor memory chip by transferring the fuse circuitry to the cell area, and to improve a focus problem in a laser repair process by redistributing the fuse circuitry under a passivation layer to a place on the passivation layer. CONSTITUTION: A semiconductor substrate(100) is prepared. The cell area(122) is formed on the semiconductor substrate. A peripheral area is formed in an area on the semiconductor substrate different from the cell area. The fuse circuitry(116) is formed on the cell area. The fuse circuitry is formed in the same plane as a pad redistribution pattern(110) on the cell area.
